Has anyone made a case out of a big aluminium tool box? if so could you tell me how you did it. Cheers

Well i think some of the purpose of modding is to have an original idea. Even if someone was succesful and could tell you how to do it it would be better if you did it yourself so it was uniqe and possible better. If you do plan on doing it all you should have to do is put something in there to keep the motherboard from touching the metal. The rest is all up to you.
